Synergistic inhibitory effects of STI571 and AG490 on BCR-ABL-expressing cell lines.
(A) Experiments using the cell line FDrv210H (18-hour incubation in inhibitors), titrating STI571 in a constant concentration of AG490. In panels A and B, solid (+IL-3) and open (−IL-3) symbols identify curves for varying concentrations of AG490 alone (●,○) STI571 alone (▴,▵), and serial dilutions of STI571 in a constant concentration AG490 [5 μM] (♦,⋄). (B) Experiment using the cell line 32Dp210 (18-hour incubation in inhibitors), titrating STI571 in a constant concentration of AG490. (C) For a constant STI571 concentration (0 or 0.01 μM), AG490 was added at the concentrations shown (MO7p210 cell line; 18-hour incubation in inhibitors without GM-CSF).
